The accompanying Condensed Consolidated Financial Statements of RF Micro Devices, Inc. and Subsidiaries (together, the
Company or RFMD) have been prepared in conformity with accounting principles generally accepted in the United States. The preparation of these financial statements requires management to make estimates and assumptions, which
could differ materially from actual results. In addition, certain information or footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been
condensed, or omitted, pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). In the opinion of management, the financial statements include all adjustments (which are of a normal and recurring nature)
necessary for the fair presentation of the results of the interim periods presented. These Condensed Consolidated Financial Statements should be read in conjunction with the Companys audited consolidated financial statements and notes thereto
included in the Companys Annual Report on Form 10-K for the fiscal year ended March 31, 2012.

The Condensed Consolidated Financial
Statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.

The Company uses a 52- or 53-week fiscal year ending on the Saturday closest to March 31 of each year. The first fiscal quarter of each year ends on the Saturday closest to June 30, the second
fiscal quarter of each year ends on the Saturday closest to September 30 and the third fiscal quarter of each year ends on the Saturday closest to December 31.

In the first quarter of fiscal 2013, the Company adopted amended standards that increase the prominence of items reported in other comprehensive income. These amended standards eliminate the option to
present components of other comprehensive income as part of the statement of changes in stockholders equity and require that all changes in stockholders equityexcept investments by, and distributions to, ownersbe presented
either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The adoption of these amended standards did impact the presentation of other comprehensive income, as we have elected to present two
separate but consecutive statements, but did not have an impact on our financial position or results of operations.

The following table sets forth a reconciliation of the numerators and denominators in the computation of basic and diluted net
(loss) income per share (in thousands, except per share data):

In the computation of diluted net loss per share for the three months ended June 30, 2012, all outstanding stock options were
excluded because the effect of their inclusion would have been anti-dilutive. In the computation of diluted net income per share for the three months ended July 2, 2011, outstanding stock options to purchase approximately 7.7 million
shares were excluded because the exercise price of the options was greater than the average market price of the underlying common stock and the effect of their inclusion would have been anti-dilutive.

The computation of diluted net (loss) income per share does not assume the conversion of the Companys $200 million initial aggregate principal
amount of 0.75% Convertible Subordinated Notes due 2012 (the 2012 Notes) or the Companys $175 million initial aggregate principal amount of 1.00% Convertible Subordinated Notes due 2014 (the 2014 Notes). The 2012 Notes
became due on April 15, 2012, and the remaining principal balance of $26.5 million was paid with cash on hand.

The 2014 Notes generally
would become dilutive to earnings if the average market price of the Companys common stock exceeds approximately $8.05 per share. The maximum number of shares issuable upon conversion of the 2014 Notes as of June 30, 2012, is
approximately11.5 million shares (excluding an aggregate of $55.4 million principal amount of 2014 Notes that were previously purchased and retired by the Company), which may be adjusted as a result of stock splits, stock dividends and antidilution
provisions.

Share Repurchase

During the three months ended June 30, 2012, the Company repurchased 1.9 million shares of its common stock at an average price of $3.75 on the open market. During the three months
ended July 2, 2011, the Company repurchased 0.9 million shares of its common stock at an average price of $5.93 on the open market.

During the first quarter of fiscal 2013, the Company entered into a wafer supply agreement, under which IQE, Inc. (IQE), a
leading global supplier of advanced semiconductor wafer products and wafer services, will supply the Company with molecular beam epitaxy (MBE) and metal organic chemical vapor deposition (MOCVD) wafer starting materials. This
wafer supply agreement provides the Company with competitive wafer pricing through March 31, 2016 (see Note 10 to the Condensed Consolidated Financial Statements for further information related to this transaction). The fair value of this wafer
supply agreement will be amortized over approximately 4 years. The Company used the incremental income method to value the supply agreement, which is a discounted cash flow method within the income approach, to estimate the fair value of the wafer
supply agreement. Under this method, the fair value was estimated by discounting to present value the additional savings from expense reductions in operations at a discount rate to reflect the risk inherent in the wafer supply agreement as well as
any tax benefits.

Intangible asset amortization expense was $4.6 million for both the three months ended June 30, 2012 and July 2,
2011. The following table provides the Companys estimated future amortization expense based on current amortization periods for the periods indicated (in thousands):

Debt balances at June 30, 2012 and March 31, 2012 are as follows (in thousands):

Convertible Debt

The
2012 Notes became due on April 15, 2012, and the remaining principal balance of $26.5 million was paid with cash on hand. Also during the first quarter of fiscal 2013, the Company purchased and retired $15.4 million original principal amount of
its 2014 Notes for an average price of $98.34, which resulted in a loss of $0.7 million. In the first quarter of fiscal 2012, the Company purchased and retired $22.0 million original principal amount of its 2012 Notes for an average price of
$105.48, which resulted in a loss of approximately $0.8 million.
In accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 470-20, Debt  Debt with Conversions and
Other Options (ASC 470-20), the Company records gains and losses on the early retirement of its 2012 Notes and 2014 Notes in the period of derecognition, depending on whether the fair market value at the time of derecognition
was greater than, or less than, the carrying value of the debt.

As of June 30, 2012, the 2014 Notes had a fair value on the PORTAL Market of $117.1 million, compared to a carrying value of
$107.0 million. As of March 31, 2012, the 2014 Notes had a fair value on the PORTAL Market of $134.9 million, compared to a carrying value of $118.9 million.

Total non-cash interest expense (discount amortization) related to the Companys 2012 Notes and 2014 Notes was $1.8 million for the three months ended June 30, 2012 and $2.4 million for the
three months ended July 2, 2011.

Bank Loan

During fiscal 2008, the Company entered into a loan denominated in Renminbi with a bank in Beijing, China. In April 2012, this loan balance of $6.3 million was repaid at maturity with cash on hand.

6. INCOME TAXES

Income Tax Expense

The Companys provision for income taxes for the reporting periods ended June 30, 2012 and
July 2, 2011 has been calculated by applying an estimate of the annual effective tax rate for the full fiscal year to ordinary income or loss (pre-tax income or loss excluding unusual or infrequently occurring discrete items) for
the reporting periods.

The Companys income tax expense was $2.8 million and $2.5 million for the three months ended June 30, 2012 and three
months ended July 2, 2011, respectively. The Companys effective tax rate was (17.3)% and 21.9% for the three months ended June 30, 2012 and three months ended July 2, 2011, respectively. The Companys effective tax rate for
both the first quarter of fiscal 2013 and the first quarter of fiscal 2012 differed from the statutory rate primarily due to tax rate differences in foreign jurisdictions, state income taxes, domestic tax credits generated, and adjustments to the
valuation allowance limiting the recognition of the benefit of domestic deferred tax assets.

The valuation allowance against net deferred tax assets has increased by $3.8 million from the $112.7 million balance as of the end of fiscal 2012.
The Company intends to maintain a valuation allowance against its domestic net deferred tax asset until sufficient positive evidence exists to support its full or partial reversal. The amount of the deferred
tax assets actually realized could vary depending upon the amount of taxable income the Company is able to generate in the various taxing jurisdictions in which the Company has operations.

The Company has outstanding domestic federal and state tax net operating loss (NOLs) carry-forwards that will begin to
expire in fiscal 2019 and fiscal 2013, respectively, if unused. The use of the NOLs which were acquired in prior year acquisitions is subject to certain annual limitations under Internal Revenue Code Section 382 and similar state tax
provisions. In addition, the Company has U.K. loss carryovers that carry forward indefinitely.

Uncertain Tax Positions

The Companys gross unrecognized tax benefits increased from $31.7 million as of the end of fiscal 2012 to $31.8 million as of the end of the first
quarter of fiscal 2013, with the change arising from a $0.1 million increase related to tax positions taken with respect to the current fiscal year.

U.S. federal tax returns through fiscal 2009, North Carolina tax returns through fiscal 2008, and German tax returns through calendar year 2007 have been examined by their respective taxing authorities.
Subsequent tax years in each of those jurisdictions remain open for examination. Other material jurisdictions that are subject to examination by tax authorities are California (fiscal 2008 through present), the U.K. (fiscal 2008 through present),
and China (calendar year 2002 through present).

7. INVESTMENTS AND FAIR VALUE MEASUREMENTS

Available-For-Sale

The following is a summary of available-for-sale securities as of June 30, 2012 and March 31, 2012 (in thousands):

The estimated fair value of available-for-sale securities was based on the prevailing market values on
June 30, 2012 and March 31, 2012. We determine the cost of an investment sold based on the specific identification method.

The
gross realized losses recognized on available-for-sale securities for the three months ended June 30, 2012 were insignificant. There were no gross realized gains or losses recognized on available-for-sale securities for the three months ended
July 2, 2011.

The available-for-sale investments that were in a continuous unrealized loss position for less than 12 months as of
June 30, 2012 and March 31, 2012 consisted of U.S. government/agency securities with gross unrealized losses of less than $0.1 million and an aggregate fair value of approximately $62.9 million and $86.9 million, respectively. There were
no available-for-sale investments in a continuous unrealized loss position for 12 months or greater as of June 30, 2012 and as of March 31, 2012.

Fair Value Measurements

On a quarterly basis, the Company measures the fair value of its marketable securities,
which are comprised of U.S. government/agency securities, auction rate securities (ARS), and money market funds. Marketable securities are reported at fair value in cash and cash equivalents, short-term investments and long-term investments on the
Companys Condensed Consolidated Balance Sheet. The related unrealized gains and losses are included in accumulated other comprehensive income (loss), a component of shareholders equity, net of tax.

Financial Instruments Measured at Fair Value on a Recurring Basis

The fair value of the financial assets measured at fair value on a recurring basis was determined using the following levels of inputs as of June 30, 2012 and March 31, 2012 (in thousands):

ARS are debt instruments with interest rates that reset through periodic short-term auctions. The
Companys Level 2 ARS are valued at par based on quoted prices for identical or similar instruments in markets that are not active.

Financial Instruments Measured at Fair Value on a Nonrecurring Basis

The Companys non-financial assets, such as intangible assets, and property and equipment, are measured at fair value when there is an indicator of impairment and recorded at fair value only when an
impairment charge is recognized. The Company did not have any material non-financial assets or liabilities measured at fair value during the three months ended June 30, 2012 and July 2, 2011.

Financial Instruments Not Recorded at Fair Value

For financial instruments that are not recorded at fair value (such as the Companys convertible subordinated notes), the Company discloses the fair value in its Notes to the Condensed
Consolidated Financial Statements.The fair values of the Companys convertible subordinated notes are measured using a Level 1 valuation technique, which are obtained from the Private Offerings, Resale and Trading through Automated
Linkages (PORTAL) Market. See Note 5 to the Condensed Consolidated Financial Statements for the fair value disclosure of the Companys convertible subordinated notes.

8. RECENT ACCOUNTING PRONOUNCEMENTS

In June 2011, the FASB issued Accounting Standards Update (ASU) 2011-05 Presentation of Comprehensive
Income (ASU 2011-05). ASU 2011-05 allows an entity to present the components of net income and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but
consecutive statements. The updated guidance eliminates the current option to report other comprehensive income and its components in the statement of changes in equity. While ASU 2011-05 changes the presentation of comprehensive income, there are
no changes to the components that are recognized in net income or other comprehensive income under current accounting guidance. In December 2011, the FASB issued ASU 2011-12 Comprehensive Income (Topic 220): Deferral of the Effective Date for
Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05 (ASU 2011-12), which defers only those changes in ASU 2011-05 that relate to
the presentation of reclassification adjustments. The new guidance is effective on a retrospective basis for financial statements issued for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2011. The
Company adopted this guidance in the first quarter of fiscal 2013 by presenting Condensed Consolidated Statements of Comprehensive (Loss) Income after the Condensed Consolidated Statements of Operations. Because this standard only affects the
display of comprehensive income and does not affect what is included in comprehensive income, this standard did not have a material effect on the Companys Condensed Consolidated Financial Statements.

In September 2011, the FASB issued ASU No. 2011-08, IntangiblesGoodwill and Other (Topic 350), Testing Goodwill for Impairment
(ASU 2011-08). ASU 2011-08 permits an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether
it is necessary to perform the two-step goodwill impairment test described in Topic 350. The qualitative assessment is optional, allowing companies to go directly to the quantitative assessment. The amendments in this update are effective for annual
and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. The Company adopted this guidance in the first quarter of fiscal 2013. The adoption of this guidance did not have a material effect on the
Companys financial position, results of operations or financial statement disclosures as the value of goodwill will not be affected by the adoption of this standard.

RFMDs operating segments as of June 30, 2012 are its Cellular Products Group (CPG), Multi-Market Products Group (MPG) and
Compound Semiconductor Group (CSG).

CPG is a leading global supplier of cellular radio frequency (RF) components, which perform various
functions in the cellular front end section, located between the transceiver and the antenna. These components are increasingly required in next-generation 3G and 4G devices, and they include power amplifier (PA) modules, transmit modules, antenna
control solutions, antenna switch modules, switch filter modules and switch duplexer modules. CPG supplies its broad portfolio of cellular RF components into a variety of mobile devices including smartphones, handsets, netbooks, notebooks, tablets
and USB modems.

MPG is a leading global supplier of a broad array of RF components, such as PAs, low noise amplifiers, variable gain
amplifiers, high power gallium nitride (GaN) transistors, attenuators, mixers, modulators, switches, voltage-controlled oscillators (VCOs), phase locked loop modules, circulators, isolators, multi-chip modules, front end modules, and a range
of military and space components (amplifiers, mixers, VCOs, power dividers and transformers). Major communications applications include mobile wireless infrastructure (2G, 3G and 4G), point-to-point and microwave radios, WiFi (infrastructure and
mobile devices), and cable television wireline infrastructure. Industrial applications include Smart Energy/AMI, private mobile radio, and test and measurement equipment. Aerospace and defense applications include military communications, radar and
electronic warfare, as well as space communications.

CSG is a new business group established to leverage RFMDs compound semiconductor
technologies and related expertise in RF and non-RF end markets and applications. CSG provides RFMDs foundry services for both gallium arsenide (GaAs) and GaN technologies.

As of June 30, 2012, the Companys reportable segments are CPG and MPG. CSG does not
currently meet the quantitative threshold for an individually reportable segment under ASC 280-10-50-12 and is therefore included in the other operating segment line in the following tables. CPG and MPG are separate reportable segments
based on the organizational structure and information reviewed by the Companys Chief Executive Officer, who is the Companys chief operating decision maker (or CODM), and are managed separately based on the end markets and applications
they support. The CODM allocates resources and assesses the performance of each operating segment primarily based on non-GAAP operating income (loss) and non-GAAP operating income (loss) as a percentage of revenue.

The All other category includes operating expenses such as stock-based compensation, amortization of purchased intangible
assets, loss on asset transfer transaction, net restructuring costs, and other miscellaneous corporate overhead expenses that the Company does not allocate to its reportable segments because these expenses are not included in the segment operating
performance measures evaluated by the Companys CODM. The CODM does not evaluate operating segments using discrete asset information. The Companys operating segments do not record inter-company revenue. The Company does not allocate gains
and losses from equity investments, interest and other income, or taxes to operating segments. Except as discussed above regarding the All other category, the Companys accounting policies for segment reporting are the same as for
RFMD as a whole.

During the first quarter of fiscal 2013, the Company entered into an asset transfer agreement with IQE under which it transferred its
MBE operations (located in Greensboro, North Carolina) to IQE. The transaction with IQE was intended to lower the Companys manufacturing costs, strengthen its MOCVD supply chain and provide it with access to newly developed wafer starting
process technologies. The assets transferred to IQE had a total book value of approximately $24.4 million (which were written off during the first quarter of fiscal 2013) and included the Companys leasehold interest in the real property,
building and improvements used for the facility and machinery and equipment located in the facility. In addition, the Company wrote-off approximately $1.0 million of MPG-related goodwill as a result of this transaction. The asset transfer agreement
contains standard representations, warranties, covenants and indemnities of the parties for transactions of this type.

In conjunction with
the asset transfer agreement, the Company and IQE entered into a wafer supply agreement under which IQE will supply the Company with MBE and MOCVD wafer starting materials. This wafer supply agreement, which is recorded as an intangible asset on the
Companys Condensed Consolidated Balance Sheet, has a fair value of approximately $20.4 million (see Note 4 to the Condensed Consolidated Financial Statements for further information related to the fair value of the supply agreement). The wafer
supply agreement provides the Company with competitive wafer pricing through March 31, 2016. The Company has agreed to minimum purchase commitments of approximately $55.7 million, at discounted wafer prices, for the first two years of the
supply agreement.

Approximately 70 employees at the Companys MBE facility became employees of IQE as part of the transaction described
above. In addition, the lease related to the MBE facility for the real property and related improvements was assumed by IQE. The difference in the value of consideration received and consideration transferred was recorded in other operating
expense and reduced the Companys pre-tax income in the first quarter of fiscal year 2013 by approximately $5.0 million. The Company does not expect to incur any additional material costs related to the disposal of the MBE assets, the
assumption of the lease by IQE or the transfer of RFMD employees to IQE.

OVERVIEW

The following Managements Discussion and Analysis (MD&A) is
intended to help the reader understand the consolidated results of operations and financial condition of RF Micro Devices, Inc. MD&A is provided as a supplement to, and should be read in conjunction with, our Condensed Consolidated Financial
Statements and accompanying notes.

We are a recognized global leader in the design and manufacture of high-performance radio frequency (RF)
components and compound semiconductor technologies. Our products enable worldwide mobility, provide enhanced connectivity and support advanced functionality in the mobile device, wireless infrastructure, wireless local area network (WLAN or WiFi),
cable television (CATV)/broadband, Smart Energy/advanced metering infrastructure (AMI), and aerospace and defense markets. We are recognized for our diverse portfolio of semiconductor technologies and RF systems expertise, and we are a preferred
supplier to the worlds leading mobile device, customer premises and communications equipment providers.

We design, develop, manufacture
and market our products to both domestic and international original equipment manufacturers and original design manufacturers in both wireless and wired communications applications, in each of our following operating segments.



Cellular Products Group (CPG) is a leading global supplier of cellular radio frequency (RF) components which perform various functions in the cellular
front end section, located between the transceiver and the antenna. These components are increasingly required in next-generation 3G and 4G devices, and they include power amplifier (PA) modules, transmit modules, antenna control solutions, antenna
switch modules, switch filter modules and switch duplexer modules. CPG supplies its broad portfolio of cellular RF components into a variety of mobile devices, including smartphones, handsets, netbooks, notebooks, tablets and USB modems.



Multi-Market Products Group (MPG) is a leading global supplier of a broad array of RF components, such as PAs, low noise amplifiers, variable gain
amplifiers, high power GaN transistors, attenuators, mixers, modulators, switches, voltage-controlled oscillators (VCOs), phase locked loop modules, circulators, isolators, multi-chip modules, front end modules, and a range of military and
space components (amplifiers, mixers, VCOs, power dividers and transformers). Major communications applications include mobile wireless infrastructure (2G, 3G and 4G), point-to-point and microwave radios, WiFi (infrastructure and mobile devices),
and cable television wireline infrastructure. Industrial applications include Smart Energy/AMI, private mobile radio, and test and measurement equipment. Aerospace and defense applications include military communications, radar and electronic
warfare, as well as space communications.



Compound Semiconductor Group (CSG) has been established to leverage our compound semiconductor technologies and related expertise in RF and non-RF end
markets and applications. CSG provides RFMDs foundry services for both GaAs and GaN technologies.

As of
June 30, 2012, our reportable segments are CPG and MPG. CSG does not currently meet the quantitative threshold for an individually reportable segment under ASC 280-10-50-12. These business segments are based on the organizational structure and
information reviewed by our Chief Executive Officer, who is our chief operating decision maker (or CODM), and are managed separately based on the end markets and applications they support. The CODM allocates resources and assesses the performance of
each operating segment primarily based on operating income (loss) and operating income (loss) as a percentage of revenue.

Quarterly revenue decreased 5.4% as compared to the first quarter of fiscal 2012, primarily due to lower demand for our wireless infrastructure
products and lower demand for our 2G products as the market transitions to 3G products. These decreases were partially offset by increased sales of our 3G/4G cellular components (including our PowerSmart® family of products, our new ultra-high efficiency 3G/4G power amplifiers and our new switch-based products).



Gross margin for the quarter was 31.7% as compared to 36.5% for the first quarter of fiscal 2012. The decrease was due to erosion in average
selling prices as well as lower factory utilization rates and increased inventory reserves. These decreases were partially offset by a favorable product mix toward higher margin 3G/4G products and switch-based products.



During the first quarter of fiscal 2013, we entered into an asset transfer agreement with IQE under which we transferred our Molecular Beam Epitaxy
(MBE) wafer starting material operations to IQE in exchange for a wafer supply agreement, which resulted in a loss of approximately $5.0 million.



Operating loss was $12.9 million for the first quarter of fiscal 2013 as compared to operating income of $14.9 million for the first quarter of fiscal
2012.



Cash flow from operations was $15.6 million for the first quarter of fiscal 2013 as compared to $19.1 million for the first quarter of fiscal 2012.



RESULTS OF OPERATIONS

Consolidated

The following table presents a summary of our results of operations for the three months ended June 30, 2012 and July 2, 2011.

Our overall revenue decreased during the three months ended June 30, 2012 as
compared to the three months ended July 2, 2011, primarily due to lower demand for our wireless infrastructure products, and lower demand for our 2G products as the market transitions to 3G products. Sales of our 3G/4G cellular components
(including our PowerSmart® family of products, our new ultra-high efficiency 3G/4G power amplifiers and our new
switch-based products) partially offset these declines for the three months ended June 30, 2012.

Our overall gross margin for the three
months ended June 30, 2012 decreased as compared to the three months ended July 2, 2011, due to erosion in average selling prices, as well as lower factory utilization rates and increased inventory reserves. The decrease was partially
offset by a favorable product mix toward higher margin 3G/4G products and switch-based products.

Our overall operating loss was
$12.9 million for the three months ended June 30, 2012, compared to operating income of $14.9 million for the three months ended July 2, 2011. This decrease was due to lower revenue as well as increased operating expenses, which
are primarily due to the loss related to the asset transfer transaction of approximately $5.0 million (see Note 10 to the Condensed Consolidated Financial Statements), as well as expenses associated with new product development for 3G/4G mobile
devices and increases in headcount and related personnel expenses.

Operating Expenses

Research and development expenses increased for the three months ended June 30, 2012, as compared to the three months ended July 2, 2011,
primarily due to expenses resulting from new product development for 3G/4G mobile devices as well as increased investments targeting customer diversification.

Marketing and selling expenses increased for the three months ended June 30, 2012 as compared to the three months ended July 2, 2011, primarily due to an increase in headcount and related
personnel expenses in support of our customer diversification efforts and in support of our new products for 3G/4G mobile devices.

General
and administrative expenses increased for the three months ended June 30, 2012 as compared to the three months ended July 2, 2011, primarily due to legal expenses and consulting expenses for tax-related initiatives.

Other operating expense increased for the three months ended June 30, 2012 as compared to the three months ended July 2, 2011, primarily due to
the transfer of our MBE wafer growth operations to IQE. The difference in the value of consideration received and the consideration transferred was recorded in other operating expense and reduced our pre-tax income in the first quarter
of fiscal 2013 by approximately $5.0 million.

The increase in CPG revenue for the three months ended June 30, 2012 as compared to the three
months ended July 2, 2011, was primarily due to increased sales of our 3G/4G cellular components (including our
PowerSmart® family of products, our new ultra-high efficiency 3G/4G power amplifiers and our new switch-based
products) which was partially offset by lower demand for 2G products as the market transitions to 3G products. The decrease in operating income for the three months ended June 30, 2012 as compared to the three months ended July 2, 2011,
was primarily due to increased expenses related to new product development for 3G/4G mobile devices and lower gross margins primarily related to erosion in average selling prices, lower factory utilization rates and increased inventory reserves.
These decreases were partially offset by increased margins as a result of favorable product mix towards higher margin 3G/4G products and switch-based products.

The decrease in MPG revenue for the three months ended June 30, 2012 as compared to the three months ended
July 2, 2011, was primarily due to lower demand for our wireless infrastructure products. The decrease in MPG operating income for the three months ended June 30, 2012 as compared to the three months ended July 2, 2011, was primarily
due to lower revenue and lower gross margins resulting from erosion in average selling prices, lower factory utilization rates and increased inventory reserves. These decreases were partially offset by increased margins as a result of favorable
product mix towards higher margin products as well as reduced operating expenses.

Statements for a reconciliation of segment operating income (loss) to the consolidated operating income (loss) for the three months ended June 30, 2012 and July 2, 2011.

Interest Expense

Interest expense decreased for the three months ended June 30, 2012 as compared to the three months ended July 2, 2011, primarily due to lower debt balances. During the first quarter of fiscal
2013, our 2012 Notes became due and the remaining principal balance of $26.5 million was paid. In addition, we purchased and retired $15.4 million original principal amount of our 2014 Notes during the first quarter of fiscal 2013.

Our interest expense included cash interest of $0.4 million for the three months ended June 30, 2012 compared to cash interest of $0.6 million for
the three months ended July 2, 2011.

Loss on the Retirement of Convertible Subordinated Notes

During the first quarter of fiscal 2013, we purchased and retired $15.4 million original principal amount of our 2014 Notes for an average price of
$98.34, which resulted in a loss of $0.7 million as a result of applying ASC 470-20. During the first quarter of fiscal 2012, we purchased and retired $22.0 million original principal amount of our 2012 Notes for an average price of $105.48, which
resulted in a loss of approximately $0.8 million as a result of applying ASC 470-20. ASC 470-20 requires us to record gains and losses on the early retirement of our 2012 Notes and our 2014 Notes in the period of derecognition, depending on whether
the fair market value at the time of derecognition was greater than, or less than, the carrying value of the debt.

Other Income

The decrease in other income for the three months ended June 30, 2012 is primarily related to the foreign currency exchange rate
impact on the Sterling, Renminbi (or Yuan) and Euro as it relates to the changes in our local currency denominated balance sheet accounts.

Our provision for income taxes for the reporting periods ended June 30, 2012 and July 2, 2011 has been calculated by applying an estimate of the annual effective tax rate for the full fiscal
year to ordinary income or loss (pre-tax income or loss excluding unusual or infrequently occurring discrete items) for the reporting periods.

Income tax expense for the three months ended June 30, 2012 was $2.8 million, which is comprised primarily of tax expense related to international operations and changes in the domestic deferred tax
asset valuation allowance, offset by a tax benefit related to domestic operations. Income tax expense for the three months ended July 2, 2011 was $2.5 million, which is comprised primarily of tax expense related to domestic and international
operations, offset by tax benefits related to changes in the domestic deferred tax asset valuation allowance.

The valuation allowance against
net deferred tax assets has increased by $3.8 million from the $112.7 million balance as of the end of fiscal 2012. We intend to maintain a valuation allowance against the domestic net deferred tax asset until sufficient positive evidence exists to
support its full or partial reversal. The amount of the deferred tax assets actually realized could vary depending upon the amount of taxable income we are able to generate in the various taxing jurisdictions in which we have operations.

LIQUIDITY AND CAPITAL RESOURCES

We have
funded our operations to date through sales of equity and debt securities, bank borrowings, capital equipment leases and revenue from product sales. Through public and Rule 144A securities offerings, we have raised approximately $1,053.3 million,
net of offering expenses. As of June 30, 2012, we had working capital of approximately $399.7 million, including $127.1 million in cash and cash equivalents, compared to working capital of approximately $402.7 million at July 2, 2011,
including $122.7 million in cash and cash equivalents. As of June 30, 2012, our total cash, cash equivalents and short-term investments balance exceeded the remaining principal amount of our 2014 Notes by $130.5 million.

Our total cash, cash equivalents and short-term investments were $250.0 million as of June 30, 2012. This balance includes approximately $94.4
million held by our foreign subsidiaries. If these funds held by our foreign subsidiaries are needed for our operations in the U.S., we would be required to accrue and pay U.S. taxes to repatriate these funds. However, under our current plans, we
expect to permanently reinvest these funds outside of the U.S. and do not expect to repatriate them to fund our U.S. operations.

On
January 25, 2011, we announced that our Board of Directors authorized the repurchase of up to $200.0 million of our outstanding common stock, exclusive of related fees, commissions or other expenses, from time to time during a period commencing
on January 28, 2011 and expiring on January 27, 2013. This share repurchase program authorizes us to repurchase shares through solicited or unsolicited transactions in the open market or in privately negotiated transactions. For
the three months ended June 30, 2012, we repurchased on the open market approximately 1.9 million shares of our common stock at an average price of $3.75. During the first quarter of fiscal 2012, we repurchased approximately
0.9 million shares of our common stock at an average price of $5.93 on the open market.

Cash Flows from Operating Activities

Operating activities for the three months ended June 30, 2012 generated cash of $15.6 million, compared to $19.1 million for the
three months ended July 2, 2011. This year-over-year decrease was primarily attributable to decreased profitability and an increase in accounts receivable, which was related to the timing of shipments.

Cash Flows from Investing Activities

Net cash provided by investing activities for the three months ended June 30, 2012 was $32.8 million, compared to $7.2 million for the three months ended July 2, 2011. This change was primarily
due to an increase in the proceeds from maturities of available-for-sale securities and lower capital expenditures during the first three months of fiscal 2013 as compared to the first three months of fiscal 2012.

Cash Flows from Financing Activities

Net cash used in financing activities was $56.0 million for the three months ended June 30, 2012, compared to $35.6 million for the three months ended July 2, 2011. During the first three months
of fiscal 2013, the 2012 Notes became due and the remaining principal balance of $26.5 million was paid with cash on hand and we also repurchased and retired $15.4 million original principal amount of our 2014 Notes. In addition, the bank loan
became due and the remaining loan balance of $6.3 million was paid with cash on hand.

Bank Loan During fiscal 2008, we entered into a loan denominated in Renminbi with a bank in Beijing, China. In April 2012, this loan balance of $6.3 million was repaid at maturity with cash
on hand.

Convertible DebtThe 2012 Notes became due on April 15, 2012 and the remaining principal balance of $26.5 million
plus interest of $0.1 million was paid with cash on hand.

During the first quarter of fiscal 2013, we purchased and retired $15.4 million
original principal amount of our 2014 Notes for an average price of $98.34, which resulted in a loss of $0.7 million as a result of applying ASC 470-20.

As of June 30, 2012, the 2014 Notes had a fair value on the PORTAL Market of $117.1 million, compared to a carrying value of $107.0 million. As of March 31, 2012, the 2014 Notes had a fair value
on the PORTAL Market of $134.9 million, compared to a carrying value of $118.9 million.

We may from time to time seek to retire or purchase
additional amounts of our outstanding convertible notes through cash purchases or exchanges for equity securities, in open market purchases, privately negotiated transactions or otherwise. Such purchases or exchanges, if any, will depend on
prevailing market conditions, our liquidity requirements, contractual restrictions and other factors and the amounts involved may be material.

Wafer Supply AgreementDuring the first quarter of fiscal 2013, we entered into an asset transfer agreement with IQE under which we
transferred our Molecular Beam Epitaxy (MBE) wafer growth operations (located in Greensboro, North Carolina) to IQE. The transaction with IQE was intended to lower our manufacturing costs, strengthen our MOCVD supply chain and provide us with access
to newly developed wafer starting process technologies. The assets transferred to IQE included our leasehold interest in the real property, building and improvements used for the facility and machinery and equipment located in the facility.
Approximately 70 employees at our MBE facility became employees of IQE as part of the transaction. In conjunction with the asset transfer agreement, we entered into a wafer supply agreement with IQE under which IQE will supply us with competitively
priced MBE and MOCVD wafer starting materials through March 31, 2016. We have agreed to minimum purchase commitments of approximately $55.7 million for the first two years of the wafer supply agreement. (See Note 10 to the Condensed
Consolidated Financial Statements for further details).

Capital CommitmentsAt June 30, 2012, we had short-term capital
commitments of approximately $4.9 million.

Future Sources of FundingOur future capital requirements may differ materially from
those currently anticipated and will depend on many factors, including, but not limited to, volume pricing concessions, capital improvements, demand for our products, technological advances and our relationships with suppliers and customers. Based
on current and projected levels of cash flow from operations, we believe that we have sufficient liquidity to meet both our short-term and long-term cash requirements. However, if current economic conditions or other factors materially reduce the
demand for our products, or in the event that growth is faster than we had anticipated, operating cash flows may be insufficient to meet our needs. If existing resources and cash from operations are not sufficient to meet our future requirements or
if we perceive conditions to be favorable, we may seek additional debt or equity financing, additional credit facilities, enter into sale-leaseback transactions or obtain asset-based financing. We cannot be sure that any additional equity or debt
financing will not be dilutive to holders of our common stock. Further, we cannot be sure that additional equity or debt financing, if required, will be available on favorable terms, if at all, particularly given the current macroeconomic
conditions.

LegalWe are involved in litigation and other legal proceedings in the ordinary course of business as well as the
matter identified below. No liability has been established in the financial statements regarding current litigation as the potential liability, if any, is not probable or cannot be reasonably estimated.

On February 14, 2012, Peregrine Semiconductor Corporation (Peregrine) filed an action in the United States District Court for the
Central District of California against the Company, alleging infringement of five Peregrine U.S. patents. On April 13, 2012, Peregrine filed a notice of voluntary dismissal of this Central District of California action without prejudice. On
February 14, 2012, Peregrine filed a complaint in the United States International Trade Commission (ITC) naming the Company as a proposed respondent and seeking institution of an investigation into alleged patent infringement in
import trade with respect to the Peregrine patents. The ITC investigation was initiated on June 7, 2012 and is ongoing. On April 13, 2012, Peregrine filed another action against the Company in the United States District Court for the
Southern District of California, asserting infringement of the Peregrine patents. On April 16, 2012, the Company filed a declaratory judgment lawsuit against Peregrine in the United States District Court for the Middle District of North
Carolina, requesting a

declaratory judgment that the Company has not infringed the Peregrine patents, and that the Peregrine patents are invalid. Both District Court actions have been stayed pending resolution of
the ITC proceeding. The parties are currently engaged in discovery matters with respect to the ITC proceeding. The Company intends to vigorously defend its position that it has not infringed any valid claim of the Peregrine patents in each of the
above-referenced legal proceedings.

TaxesWe are subject to income and other taxes in the United States and in numerous foreign
jurisdictions. Our domestic and foreign tax liabilities are subject to the allocation of revenues and expenses in different jurisdictions. Additionally, the amount of taxes paid is subject to our interpretation of applicable tax laws in the
jurisdictions in which we operate. We are subject to audits by tax authorities. While we endeavor to comply with all applicable tax laws, there can be no assurance that a governing tax authority will not have a different interpretation of the law
than we do or that we will comply in all respects with applicable tax laws, which could result in additional taxes. There can be no assurance that the outcomes from tax audits will not have an adverse effect on our results of operations in the
period during which the review is conducted.

CONTRACTUAL OBLIGATIONS

Other than as set forth below, there have been no material changes outside the ordinary course of business to our contractual obligations and commitments as set forth in our Annual Report on Form 10-K for

ITEM 4. CONTROLS AND PROCEDURES.

As of the end of the
period covered by this report, the Companys management, with the participation of the Companys Chief Executive Officer and the Chief Financial Officer, evaluated the effectiveness of the Companys disclosure controls and procedures
in accordance with Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the Exchange Act). Based upon their evaluation, the Chief Executive Officer and the Chief Financial Officer concluded that the Companys disclosure
controls and procedures were effective for the purpose of ensuring that the information required to be disclosed in the reports that the Company files or submits under the Exchange Act with the Securities and Exchange Commission (the SEC)
(i) is recorded, processed, summarized and reported within the time periods specified in the SECs rules and forms, and (ii) is accumulated and communicated to the Companys management, including its Chief Executive Officer and
Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

In addition, there were no changes in the Companys internal control over financial reporting that
occurred during the period covered by this report that have materially affected, or are reasonably likely to materially affect, the Companys internal control over financial reporting.

PART II  OTHER INFORMATION

ITEM 1A. RISK FACTORS.

In addition to the other information set forth in this report and in our other reports and statements that we file with the SEC, including our quarterly reports on Form 10-Q, careful consideration should
be given to the factors discussed in Part I, Item 1A., Risk Factors in our Annual Report on Form 10-K for the fiscal year ended March 31, 2012, which could materially affect our business, financial condition or future results.
The risks described in our Annual Report on Form 10-K are not the only risks that we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business,
financial condition and/or operating results.
